This invention relates to a dumpingy bailer whereby a quantity ot cement can be released in a bored hole atany desired depth.

An object oi' my invention is-to provide a bailer.

while the bailer is moved downwardlyln the well, and which is opened to release cement by a short upward pull of the tubing.

Another object is to which is to provide a bailer which can be both opened well.

Still another object is to provide a novel bailer .which is simple in construction and inexpensive to manufacture.

' Other objects. advantagesand features o! invention may appear from thel accompanying l0 drawing, the subjoined detailed description and the appended claims. In, the drawing' l l* Figure 1 is a side elevation of my bailer.

Figure 2 is a longitudinal sectional view of the- --25 same. l

Figure 3 is a side elevation or the upper collar..

Figure 4 is an enlarged fragmentary longitudlnal sectional view of the lower collar.

Referring'morel particularly to the drawing, thev and the bottom o! the plug 5.

A sleeve 6 is slidably mounted on the tube 1 and has a limited longitudinal movement. A pin 'I projects outwardly from the tube 1 into a slot 8 rotation relative to the tube 1. The sleeve 6 is provided with a plurality of openings 9 which are adapted to match the ports 4 when the tube is in the lowermost position: The tube is limited in its downward movement by the plug 3. When the openings 4 and 9 are in juxtaposition, cement will ilow from the bailer.

When the tube is being run into the hole, the sleeve 6 is held in .raised position and the ports '55 4 and 9 are out of registry by means of the folprovide a novel bailer, theA are removably mounted,

and closed while it is in the bail `ing the ring within in the sleeve, thereby holding the sleeve against "7 Claims. (Cl. 168-19) gage 'the side 'of the hole or the casing, and thus hold the sleeve 6 in the position shown in Fig.'2. When the point is reached where it is desiredto place the cement, the tubing is pulled upwardly, and due to the frictional engagement of upper end of the sleeve 6to the collar 11 in the the i'errule 16. l

The collar ll-which holds the upper ends of $53 the arms 10,'is formed grooves 18. A notch 19 is formed in each of vthe grooves 18 to receive thel inturned ends of the arms 10.

A nut 20 screws onto the collar 11 over the 90 upper endsy of the arms 10 tosecurely hold said varms in the grooves 18. It will be evident that' by unscrewing the nuts 17 and 20, the arms 1Q can bequickly and easily removed, and replaced.

A coupling 21 at the upper end of the tube Y1 is engaged by the collar 11 in the raised position oi the tube 6 to limit the upward movement of said tube..

Having described my invention, nI claim:

1. A dumping bailer comprising a tube. said tube having an outlet port therein, a sleeve surengaging the wall of the hole.

2. A dumping bailer comprising a tube, said tube having an outlet port therein, a. sleeve surrounding said tube and slidable thereon, said l-1'0 A Mia sleeve having a hole therein adapted to move into and out o! registry with said port, a collar slidably mounted on the tube, spring arms attached to said sleeve and collar, said arms frictionally engaging the wall of the hole, and means engaging the lsleeve whereby it is held against rotation relative to the tube.

3. A dumping bailer comprising a. tube closed at the bottom and open at the top, said tube having a port therein adjacent the lower end, a sleeve slidably mounted on the tube, said sleeve having a hole therein adapted to move into and out oi registry with said port, means limiting the longitudinal movement oi said sleeve relative to the tube, a collar slidably mounted on the tube, and .spring arms removably secured to said collar and to the sleeve. 1 ,v

4. A dumping bailer comprising a tube, said tube having an outlet port therein', a sleeve surrounding said tube and slidable thereon, said sleeve having a hole therein adapted to move into and out of registry with said port, a collar slidably mounted on the tube, a ring surrounding the sleeve, said ring having slots therein, a nut screwed into the sleeve against the ring, spring arms, the lower end of each arm being bent to enter one o! the slots, a ferrule iitting around the lower ends of the spring arms, said collar having grooves formed therein, the upper end of each of the arms iltting into a groove, and a nut screwed onto the collar whereby theupper ends of the arms are held in said collar, said arms engaging the walls of the well. A

5. A dumping bailer comprising a .-tube, said tube having an outlet port therein, a sleeve surrounding said tube and slidable thereon, said sleeve having a hole therein adapted to move into and out of registry with said port, a collar slidably mounted on the tube, a ring surrounding the sleeve, said ring having slots therein, a nut screwed into' the sleeve against the ring, spring arms, the lower end oi each arm being bent to enter one of the slots, a ferrule iitting around the lower ends of the spring arms, said collar having grooves iormed therein, the upper end of each o! the arms .fittinginto a groove, a nut screwed onto the collar whereby the upper ends oi the arms are held in said collar, said arms engaging the walls of the well, said sleeve having a slot formed therein and a pin projecting from the tube into the slot whereby the sleeve is held against rotation relative to the tube. s,

6. A dumping bailer comprising a tube closed at the bottom and open at the top, said tube having a port therein adjacent the lower end, a sleeve slidably mounted on the tube, said sleeve having a hole therein adapted to move into and out of registry with said port, means limiting the longitudinal movement of said sleeve relative to the tube, a collar slidably mounted on the tube, a ring surrounding the sleeve, said. ring having slots therein, a nut screwed into the sleeve against the ring, spring arms, the lower end of each arm being bent to enter one of the slots, a. ferrule fitting around the lower ends of the spring arms, said collar having grooves formed therein, the upper end of each of the arms tting into a groove, and a nut screwed onto the collar whereby the upper ends of vthe arms are held in said collar, said arms engaging the walls of the well.

'7. A dumping bailer comprising a tube closed at the bottom and open at the top, said tube having a port therein adjacent the lower end, a sleeve slidably mounted on the tube, said sleeve having a hole therein adapted to move into and out of registry with said port, means limiting the longitudinal movement of said sleeve relative to the tube, a collar slidably mounted'on the tube, a ring surrounding the sleeve, said ring having slots therein, a nut screwed into the sleeve against the ring, spring arms, the lower end of each arm being benty to enter one'of the slots, a ferrule fitting around the lowerv ends of the spring arms, said collar having grooves formed therein, -the upper end of each of the arms iitting into a groove, a nut screwedonto the collar whereby the upper ends of the arms are held in said collar, said arms engaging the walls of the well, said sleeve having a slot formed therein, and a pin projecting from the tube into the slot whereby the sleeve is held against rotation relative to the tube.
